Perfect as an appetizer, side, or even a light main course, these creamy spinach stuffed Portobello mushrooms are a crowd-pleaser with a gourmet twist. The wood-fired oven takes them to the next level, imparting a smoky depth that you just can’t replicate in a standard kitchen oven. Let’s dive into this easy yet robust recipe!
Why Use a Wood-Fired Oven?
Wood-fired ovens have been a favorite cooking tool for centuries. They reach incredibly high temperatures while adding a distinct smoky flavor to food. This recipe benefits from the wood-fired oven's quick, intense heat, which perfectly cooks the mushrooms while creating a golden, bubbling surface on the creamy filling.
If you don’t have a wood-fired oven, no worries! We've included tips for achieving similar results in a standard oven.
Ingredients
(Serves 4-6)
For the Mushrooms:
- 4 large Portobello mushrooms, stems removed and wiped clean
- 1 tablespoon butter
For the Creamy Spinach Filling:
- 2 cups fresh spinach (or frozen spinach, thawed and drained)
- Chopped stems from Portobello mushrooms
- 3 Tablespoons of sour cream
- 2 cloves garlic, minced
- 2 tablespoons butter
- Salt and pepper to taste
Topping:
- 1/4 cup shredded mozzarella cheese
- 1/4 cup shredded Parmesan cheese
- Fresh parsley for garnish (optional)
Instructions
Step 1: Prepare the Mushrooms
- Preheat your wood-fired oven to a temperature of around 400-450°F (200-230°C). If using a standard oven, preheat to 425°F.
- Brush the Portobello mushrooms with olive oil and sprinkle with salt and pepper. Place them gill-side up on a baking sheet or cast-iron pan that’s oven-safe.
Step 2: Make the Creamy Spinach Filling
- Heat 2 tablespoons of butter in a skillet in the oven. Add the garlic and sauté for 1 minute, until fragrant. Add the chopped mushroom stems and place back in oven for an additional 3-4 minutes.
- Add the spinach and cook until wilted (if using fresh) or warmed through (if using frozen).
- Remove the spinach from heat and mix it with the sour cream until smooth and creamy. Adjust seasoning to taste.
Step 3: Assemble the Mushrooms
- Spoon the creamy spinach filling into each mushroom cap, spreading it evenly.
- Top with shredded mozzarella and parmesan cheese.
Step 4: Bake in the Wood-Fired Oven
- Place the prepared mushrooms in your wood-fired oven. Keep an eye on them—the intense heat will cook the mushrooms quickly, usually in 5-10 minutes.
- The mushrooms are done when the cheese is golden and bubbling, and the edges of the mushrooms are tender with a slight char.
Tip: Rotate the pan or mushrooms halfway through the baking process to ensure even cooking.
Step 5: Serve and Garnish
- Carefully remove the mushrooms from the oven and let them cool for a minute or two.
- Garnish with fresh parsley for a pop of color and freshness.
- Serve hot and enjoy the creamy, smoky goodness!
Notes & Substitutions
- Cheese Options: Feel free to swap out mozzarella for gouda, cheddar, or fontina for a different flavor profile.
- Add Protein: Add some cooked, crumbled bacon or shredded rotisserie chicken to the filling for extra heartiness.
- No Wood-Fired Oven? Bake the mushrooms in a preheated standard oven at 425°F for about 15-18 minutes, or until the cheese is bubbly and golden.
